The state of hybridisation of \[Cl\] atom in \[ClO_{2}^{-}\]is

A)                   \[s{{p}^{3}}\]                                  

B)                  \[s{{p}^{2}}\]

C)  \[s{{p}^{2}}d\]                

D)  \[s{{p}^{3}}\]

Correct Answer: A

Solution :

                 The structure of \[ClO_{2}^{-}\] is as In this structure there is 2a-bonds as well as two lone pairs on the central atom chlorine. Thus, it possess \[s{{p}^{3}}\] hybridisation.
